Increased rRNA gene activity during a specific window of early pea leaf development.
rRNA gene transcription rates were determined during light-mediated leaf development in Pisum sativum. The rate of transcription was observed to increase within 1 day of exposure to light and return to control levels 4 days after exposure. A striking similarity was observed between periods of elevated rRNA gene transcription and increased mitotic activity, suggesting a possible link between the two events.
